Method for processing inputs between devices and electronic device thereof

1. A wearable device that can be attached to or detached from a user, the wearable device comprising: a first display having a first size; a processor; and a memory storing instructions thereon that, when executed, allow the processor to: display, through the first display, a user interface including a first keypad; obtain a first text input through the first keypad; display at least one first text corresponding to the first text input in the user interface; transmit, to an external device that includes a second display having a second size, a request for obtaining a second text input through a second keypad displayed on the second display of the external device and supplementary information related to the first text input, the supplementary information including a type of the first keypad in the user interface and the at least one first text displayed in the user interface; receive, from the external device, the second text input obtained through the second keypad, wherein a type of the second keypad is identified as the type of the first keypad based on the supplementary information, and wherein the at least one first text is displayed with the second keypad based on the supplementary information; and display, through the first display, at least one second text corresponding to the second text input received from the external device, next to the at least one first text in the user interface, wherein the first keypad in the user interface is in an active state capable of obtaining a third text input while receiving the second text input.

2. The device of claim 1 , wherein the processor changes the type of the first keypad displayed in the first display to another type, in response to the transmission of the request and the supplementary information.

3. The device of claim 1 , wherein the processor, in response to the transmission of the request and the supplementary information, deactivates the first keypad and displays the at least one second text in an input window of the first display.

4. The device of claim 1 , wherein the processor transmits the request and the supplementary information to the external device in response to a user input in the user interface.

5. The device of claim 1 , wherein the supplementary information further includes at least one of a type of input item, a keypad language, a security level, a requested text string length, a maximum enterable length, non-enterable characters, text that is pre-input into an input window, and information on an application.

6. The device of claim 1 , wherein the processor receives the second text input in real time from the external device, or receives the second text input from the external device when the second text input is completed.

7. The device of claim 1 , wherein the first size is less than the second size.

8. An electronic device comprising: a first display having a first size; a processor; and a memory storing instructions thereon that when executed allow the processor to: receive, from an external device that includes a second display having a second size and that displays a user interface including a first keypad for obtaining a first text input through the second display, a request for obtaining a second text input and supplementary information related to the first text input, the supplementary information including a type of the first keypad in the user interface and at least one first text displayed in the user interface according to the first text input; display, through the first display, the at least one first text and a second keypad for obtaining the second text input, wherein a type of the second keypad is identified as the type of the first keypad based on the supplementary information; obtain the second text input through the second keypad; and transmit the obtained second text input to the external device, wherein at least one second text corresponding to the second text input is displayed next to the at least one first text in the user interface of the external device, and wherein the first keypad is in an active state capable of obtaining a third text input while transmitting the obtained second text input.

9. The device of claim 8 , wherein the supplementary information further includes at least one of a type of input item, a keypad language, a security level, a requested text string length, a maximum enterable length, non-enterable characters, and information on an application.

10. The device of claim 8 , wherein the processor transmits the second text input obtained through the second keypad to the external device when a character of the at least one second text is input, or when the second text input is completed.

11. The device of claim 8 , wherein the processor removes the second keypad that is displayed on the first display when the second text input through the second keypad is completed.

12. The device of claim 8 , wherein the memory stores an identification number of the external device, and the processor: executes an application based on the identification number of the external device according to the request, and transmits data by using the identification number of the external device, based on the second text input obtained through the second keypad.

13. A method of a wearable device that includes a first display having a first size, the method comprising: displaying, through the first display, a user interface including a first keypad; obtaining a first text input through the first keypad; displaying at least one first text corresponding to the first text input in the user interface; transmitting, to an external device that includes a second display having a second size, a request for obtaining a second text input through a second keypad displayed on the second display of the external device and supplementary information related to the first text input, the supplementary information including a type of the first keypad in the user interface and the at least one first text displayed in the user interface; receiving, from the external device, the second text input obtained through the second keypad, wherein a type of the second keypad is identified as the type of the first keypad based on the supplementary information, and wherein the at least one first text is displayed with the second keypad based on the supplementary information; and displaying, through the first display, at least one second text corresponding to the second text input received from the external device, next to the at least one first text in the user interface, wherein the first keypad in the user interface is in an active state capable of obtaining a third text input while receiving the second text input.

14. The method of claim 13 , further comprising: in response to the transmission of the request and the supplementary information, deactivating first the keypad; and displaying the at least one second text in an input window of the first display.

15. The method of claim 13 , further comprising changing the type of the first keypad displayed in the first display to another type, in response to the transmission of the request and the supplementary information.

16. The method of claim 13 , wherein transmitting the request and the supplementary information comprises: creating the supplementary information in response to a user input in the user interface; and transmitting the request and the created supplementary information to the external device.

17. The method of claim 13 , wherein the supplementary information further includes at least one of a type of input item, a keypad language, a security level, a requested text string length, a maximum enterable length, non-enterable characters, and information on an application.
